TAP-WRENCH.

SPECIFICATION forming part of Letters Patent No. 226,643, dated April 20, 1880,

Application filed January 29, 1880.

-or figures of reference markedthereon, which form a part of this specification.

This invention is in the nature of improvements in tap-wrenches, and is designed to afford a simple, cheap, and durable wrench, adapted to receive either an oblong or square headed tap, for general use by mechanics.

The invention relates more particularly to a stock having, if desired, changeable handles, and a slot constructed with one-half its head to receive flat or oblongheaded taps and the other half to receive square-headed taps, in combination with a follower similarly formed, whereby the wrench is adapted for use with the variously-shaped taps usually found in the machinists department.

In the drawings illustrating my invention, in the several figures of which like parts are similarly designated, Figure 1 is a plan view of one side of the wrench, showing the form of slot-head and follower adapted for flat or oblong headed taps. Fig. 2 is a similar view of the opposite side, showing the form of slothead and follower adapted for square-headed taps, with a portion of the follower broken away to illustrate the mode of connecting the follower with its adjusting-screws. Fig. 3 is a cross-section on line 00 m of Fig. 1, looking in the direction of the arrow, and showing the follower in top view; and Fig. 4: is a perspective view of the parts of the follower separated.

A designates a tap-wrench stock, of metal, and having handle-sockets a a. The handles b I) may be of wood, and preferably are of equivalent material that will be easy on the hands. These handles may be screwthreaded and inserted in correspondinglythreaded recesses in the sockets to a, or the parts a b and a b may be in one piece with the stock A. The handle or socket alis screwthreaded at c, and works in a correspondinglythreaded orifice in the part dof the stock, and the inner end of the threaded portion 0 is made with a button or disk, 0, upon which a follower, B, is secured.

The stock A is slotted at (3, into which slot the screw 0 extends, and one half or part of the head f of such slot is made with two faces, g g, extending upon parallel lines and connected by a right-angled face, as shown in Fig.

-l of the accompanying drawings, and the opposite half or part with a straight face, It, preferably provided with a right-angled notch, as shown in Fig. 2.

The follower B is made in two parts, 1 2, one of such parts, 1, having a face, i, matching the faces 9 g of the slot-head f, and the other part, 2, having a face, j, matching the straight face h of said slot-head, and, like it, having a right'angled notch. This follower has flanges is, adapted to slide upon the edges or walls lof the slotted stock. The meeting or inner faces of the two parts 1 2 of the follower are recessed, as at m n, to permit of their inclosing the button or disk 0 of the screw 0, and when so placed about such screw, within the slot 0, the said parts are united by a screw-bolt or rivet, 0, whereby the follower is secured to and may be adjusted in the slot by the movable screw-threaded handle.

It will be understood that the button 0 turns easily within the cavity formed in the follower by the recesses m n in the halves 1 2 of such follower, so as to admit of the easy and ready adjustment of the follower without l'inding in the slot. The flanges k of the follower, sliding on the walls 1 of the slot, serve to guide and steady the follower in its movement and confine it within the slot.

It will be readily understood that in using this tap-wrench the tap or die is placed, according to its oblong or square shape, on the corresponding face of the slot-head, and the 5 IOO structed with differently-shaped faces, in combination with a follower provided with correspondingly-shaped faces, and with an operating screw-handle, substantially as shown and described.

2. In a tap-wrench, a slotted stock, in combination with a screw-handle having a button, 6, and a flanged recessed follower, B, constructed in two parts, and a screw-bolt, 0, substantially as shown and described.

In testimony whereof I afiix my signature :0 in presence of two witnesses.
